Figure 9. Saco Bay Sand Budget. About 4,000,000 cubic yards of beach sand moved north in 100 years (1859-1955) from the vicinity of the Saco River jetty to the Scarborough River tidal inlet. This is about 3 times the pre-jetty transport rate and also about 3 times the sand resupply rate of the Saco River.
